Big Ideas:
Exact solutions of linear systems can be found algebraically through substitution.
A system of linear equations in slope intercept form can be solved by using the substitution property of equality.
Students will algebraically solve linear systems that have their equations in slope-intercept form by using substitution. In this task, they will use the information about one variable to solve for another and, thus, solve the linear system.
Vocabulary: substitution, slope-intercept form
